The invention relates to a vehicle and a drive axle device thereof.The drive axle device comprises a drive axle shell and two electric power assemblies, the drive axle shell is provided with a first center shaft, and the two electric power assemblies are arranged on the portions, on the two opposite sides of the first center shaft, of the drive axle shell correspondingly; each electric power assembly comprises a driving motor, a gear shifting mechanism, a planetary reducer set, a brake and a driving wheel which are sequentially arranged, the driving motors are sequentially connected with the planetary reducer sets and the brakes through half shafts, the gear shifting mechanisms are connected to the planetary reducer sets, and the planetary reducer sets are in transmission connection with the driving wheels. The two drive motors are symmetrically arranged in the drive axle shell relative to the first central axis, and at least parts of the two planetary reducer sets and the two brakes are arranged in the corresponding drive wheels respectively. According to the drive axle device, the transmission structure is simplified, the gear shifting mechanism enables a small drive motor to meet large torque output, the system is compact, the unsprung mass is light, and the transmission efficiency and the control accuracy are improved.

    本申请涉及一种车辆及其驱动桥装置,驱动桥装置包括驱动桥壳体以及两个电动力总成,驱动桥壳体具有第一中心轴,两个电动力总成分别设于驱动桥壳体在第一中心轴的相对两侧,每个电动力总成均包括依次设置的驱动电机、换挡机构、行星减速器组、制动器以及驱动轮,驱动电机通过半轴依次连接行星减速器组和制动器,换挡机构连接于行星减速器组,行星减速器组与驱动轮传动连接,其中,两个驱动电机关于第一中心轴对称地设于驱动桥壳体内,两个行星减速器组的至少部分和两个制动器分别设于对应的驱动轮内。本申请的驱动桥装置传动结构简化,存在换挡机构使较小驱动电机可满足较大扭矩输出,系统紧凑,簧下质量轻,提高了传动效率和控制精确度。
